ITIL is cornerstone of good quality ITSM
and a necessity for quality assurance. It provides a
systematic, process-based approach, supported by
procedures for key IT service management processes.
ITIL is Technology independent. ITIL gives a
detailed description of a number of important IT
practices with comprehensive checklists, tasks and
procedures that can be tailored to any IT
organization.
The ITIL series consists of several books
providing guidance on the planning, delivery and
management of quality IT services to support
business needs comprising issues pertaining to
Service Support, Service Delivery, IT Infrastructure
Management, Application Management, Business
Perspective, Security Management. ITIL has clear
definition of various terms used in ITSM in a concise
yet comprehensive manner.
ITIL provides a comprehensive set of
guidance to link the technical implementation,
operations guidelines and requirements with the
strategic management, operations management and
financial management of a modern business. Among
the benefits associated with adopting the ITIL which
have been identified by the users are improved
customer satisfaction with IT services, better
communications and information flows between IT
staff and customers, better management control over
ITSM and reduced costs in developing and
implementing procedures and practices within an
enterprise. ITIL improves the performance of
processes which are being followed in an
organization leading to high quality output.
It goes into great detail regarding the
process, implementation and the content of the key
deliverable of the Service Level Agreement (SLA)
and Service Level Requirements (SLRs).
ITIL contains tried and tested processes. It
has a quick-start approach to help in making the best
use of time and resources available and see quick
results. It led to improved productivity of the
organization itself and also of delivery of third party
services through the specification of ITIL. The well
defined ITIL processes also minimizes duplication of
efforts, dropped hand-offs and unapproved work.
Additionally, individuals gain a better understanding
of roles and responsibilities and how they each
contribute to the success of IT and the business. It
separates administrative tasks and technical tasks to
help in assigning the most appropriate resources. In
short, ITIL improves efficiency, effectiveness and
economy of the ITSM.
ITIL describes the management of IT
Services in the context of the lifecycle of those
services. The focus of ITIL today is integration of IT
into the business, assuring the delivery of business
value and the treatment of services as business assets.
ITIL describes the life of a service from conception
to retirement, within a Service Portfolio detailing
aspects of planning and development as well as
objects, specification, description and requirements
of the services in use or being offered for use through
means of the processes. Each process has a home in
the lifecycle stage book where it is most active. The
lifecycle approach gives an improved, holistic
structure within which to describe all the functions,
processes, roles and responsibilities that constitute
ITSM Best Practice.
The two basic requirements of ITSM are:
(a) Service Delivery: ITIL's Service Delivery
component includes tactical processes necessary for
planning and delivering quality IT services, which is
defined in SLA. Service Delivery best practices
address Availability Management, Capacity
Management, Service Level Management, Service
Continuity Management (contingency planning) and
Financial Management for IT Services.
(b) Service Support: ITIL's Service Support
component focuses on the operational processes that
enable companies to provide IT Support and
maintenance activities on a day-to-day, around-the-
clock basis. SeService Support Dicipline includes
Service Support Service Support disciplines include
Change Management, Configuration Management,
Problem Management, Incident Management and
Release Management (including software and
hardware control and distribution). This includes
service desk facility as single point of contact and
disaster recovery mechanism. The objective is to
minimize disruption to the business by proactive
identification and analysis of the cause of service
incidents and by managing problems to closure.
Organizations have significantly cut costs,
have improved processing time and have enhanced
their overall service provisions. Since IT is what
drives business today, service provision to customers
has a major bearing on the interests of CIOs. The
accurate measurement of service provides them with
strategic information for decision making in their
quest for return on investment and the alignment of
IT with the business.
From small organizations to multinational
enterprises and anything in between, this best
practice framework has helped many improve
efficiencies and bottom line figures, putting IT back
in business.
Objective
The main goal of this case study is to
research on the case company and do some statistical
analysis on a single unit of IT infrastructure i.e. IT
Helpdesk unit and measure both quantitative and

qualitative way for the betterment of the service
support by reducing cost but yet providing optimal
services. Aligning IT with business goals and service
objectives by focusing ITIL which separates
administrative tasks and technical tasks to help in
assigning the most appropriate resources.
Methods
In order to accomplish the aforementioned
goal, following sequential methods have been used:
• Collection of information about overall situation,
its impact and consequence in
telecommunication sector in Bangladesh from
secondary and unpublished sources, media,
internet , articles, papers or the like.
• Study and review existing services provided by
the case company and identifying proposed
services(ITIL) as the best practices which can led
to improved productivity of the organization
itself and also of delivery of third party services
through the specification of ITIL. As the well
defined ITIL processes minimizes duplication of
efforts, dropped hand-offs and unapproved work.
Additionally, individuals gain a better
understanding of roles and responsibilities and
how they each contribute to the success of IT and
the business.
• Interviewing experts from IT infrastructure and
as well as Technical and Service support
department of the case company.
• Design of a set of related components to provide
these services.
• This case study was conducted for BL by
considering the IT Auditor’s feedback and
recommendations.
Benefits Achieved by Implementing ITIL
Ultimately IT Service Management is about
maximizing the ability of IT to provide services that
are cost-effective and meet the expectations and
needs of the business.
Figure 1: Major benefits of ITIL
Analysis of Usage of ITIL Service
Management Processes
ITIL service management process comprises
of two core service sets: Service Support and Service
Delivery. These two core sets are made up of 10
disciplines listed below in Table 1:
Table 1: ITIL service management process with
purpose
Considering the above discussion on ITIL
service management process below framework in Fig
2, with any third party vendor who implement ITIL
can be adopted by BL to implement ITIL in their
organization.
Figure 2: Sample ITIL implementation team structure
In Fig 2. there should be two project
manager , one from BL and another from third party
vendor. From vendor side there should be
implementation team, trainer and consultants who
will report project manager of vendor side. On BL
side the implementation team member will be from
different IT units. They will report to project manager
during ITIL implementation stage. Both manager of
two sides will work together and follow up the
procedure jointly.
So if the case company wants to go for ITIL
practice they should form a team with specific roles
and responsibilities given in Table 2.

Table 2: Proposed Team Structure with Role &
Responsibilities
Typical ITIL Implementation Approach for
Banglalink
To implement ITIL for the case company it
will be convenient if they implement it in three
different phases according to the suggestion of ITIL
consultant as the case company is not using ITIL
right now. This is shown in Fig. 3. The description of
three different phases are :
Phase 1: This phase focused on awareness
training for decision makers as well as different
project teams.
Phase 2: It focused on real implementation,
efforts required considering ITIL framework.
Phase 3: It deals with obtaining ITIL
certification for the case company through ISO 2000
audit team.
Fig 3: Proposed implementation plan
The total plan is divided into eight different
sections which is shown in Fig.3, should be
implemented in sequential order in three different
phases. The eight different sections are:
1. Program Planning & Kickoff.
2. Baseline Assessment & Gap Analysis.
3. Action Planning & Project Scheduling.
4. ITIL processes & definition &
Implementation & Training. Ex: Request
Fulfillment, Access, Problem, Incident &
Effort Management.
Implementation & Training. Ex: KM, SWT,
R&DM, S&CM, SM, TPM.
Implementation & Training. Ex: SM, IS,
ITSC, AM, CM, SLM, SCM etc.
Implementation & Training. Ex: SE, SS,SIP
etc.
8. ISO 20000 Audit.
For the proposed three phases discussed
above the case company has collected budgetary
quotation from local vendor company which is given
in the Table 3.
Table 3: Budgetary quotation from local vendor
ROI (Return on Investment)
From the budgetary quotation presented in
Table 3, it is found that the case company requires
USD 137K to implement it. So for getting optimum
Return Of Investment, I took several interview with
Helpdesk unit General Manager and some other
helpdesk executives to collect business data for my
study purpose.
Based on the gathered information the
following calculations are made:
• Average monthly salary of Help Desk executive
is $600/month.
• Average cost per employee $7 per hour.
The example, shown in Table.4 the
following assumption are also made based on one
year data from Helpdesk Trouble Ticketing
System(TTS is a SW by which the case
company provides IT support to users through this
workflow management software. User raised problem
ticket through this software and their support agents
resolve problem through built-in workflow, so that
they can quantify how many tickets per month, per
day, per year resolved through how many agents and
which SLA time).
Table 4 also provides ticket information of one year
and from that table the following information is
found.
• Average total number of helpdesk Tickets is
12,000 per year.
• Average Downtime related incident Tickets is
1080 per Year (9% of total tickets).

• Average Recurrent related incident tickets is
1080 per Year (9% of total tickets).
• Average Configuration related incident tickets
is 2880 per Year (24% of total tickets).
• Average other tickets is 7000 per year (58% of
total tickets).
Table 4: Counting and measuring tickets from TTS
software
Using the information given on Table 4, I
just tried to find out best ROI, worst ROI and average
ROI scenario on four different ITIL processes(i.e.
configuration management, incident management,
problem management & capacity management)
which is given in Table 5.
From the analytical data in Table 5, it is
clear that if the case company will use ITIL only on
their Helpdesk unit they can return their investment
within 3year 5 months in best case scenario, 4 year
10 months for worst case scenario and 3 year 7
months for average case scenario. This case study is
done only on a single unit (IT Helpdesk) of the
company. But ITIL can be implemented on entire IT
department even for whole company. In that case
ROI can be achieved more quickly and will get more
benefit.
Limitations
In absence of proper IT framework, it may
not be ensured that banglalink’s information and
related technology supports its business objectives,
its resources are used properly and its risks are
managed appropriately.
• ITIL has been proposed to implement on IT
helpdesk unit based on one year data of trouble
ticketing system but its pros and cons would
only be projected when it is deployed.
• Another limitation is that in the absence of
adequate data due to the confidentiality of the
case company the result obtained is not the
optimum one.
Conclusion
Implementing ITIL is not a quick fix nor
will it be easy to implement. It takes a lot of thought,
commitment and hard work to successfully change
the way the IT organization does business. There
needs to be upfront planning, training and awareness,
ongoing scheduling, roles created, ownership
assigned, and activities identified in order to be
successful. Implementation and credentialing the
ITIL in ITSM requires knowledge and training. ITIL
is intended to be non-prescriptive, expecting that
organizations will have to engage ITIL processes
with their existing overall process model.
Even with a successful service operation in
place, there is still a need to consider improvements
at every opportunity. This will help protect against
losing competitive edge and will ensure that the best
possible outcomes are being achieved. Continual
Service Improvement focuses on the process
elements involved in identifying and introducing a
cycle of service management improvements.
This survey provides approximate benefit
that can be achieved but true outcome is not
quantifiable until or unless any company do proper
practice of it. The real benefit is vast than that is
estimated in my paperwork.

Table 5: ROI calculation based on Table 3 & Table 4
Future Work
Although this study was done on part of IT
Infrastructure department i.e. service support. For
achieving optimum result it can be implemented on
the whole ITIL Service Strategy; ITIL Service
Design; ITIL Service Transition; ITIL Service
Operation; and ITIL Continual Service Improvement.
A sound service strategy is essential in the creation of
high quality IT services. It provides a base upon
which to build a successful service management
function and ensures that best value is delivered to
business customers. Being a framework, it is
completely customizable for application within any
type of business or organization that has a reliance on
IT infrastructure. ITIL series consists of several
books providing guidance on the planning, delivery
and management of quality IT services to support
business needs comprising issues pertaining to
Service Support, Service Delivery, IT Infrastructure
Management, Application Management, Business
Perspective, Security Management. As per my study
there are few organizations in Bangladesh that are
using a standard framework for their IT
infrastructure. So my case study will act as a
reference to promote them in using ITIL.
